Easy Cover Locking mechanism for Portable PCs

Background:

Personal computers (PCs) became one of commodities for everyone in digitalized information age as a result of widely-spread Internet. Most of portable PCs, including PDAs and handy electronic dictionaries, are designed with the openable and closable structure of "clamshell" enclosure and require a locking mechanism for binding foldable LCD panel and CPU main body each other. Locking mechanism is categorized into 3 type by operation knob location/quantity below;
(1) One pair of Operation knob/latch per each side of PC enclosure
(2) Two pairs of Operation Knobs/latches on Front face's both ends of PC enclosure
(3) One pair of Operation Knob/latches in either central or rightish position on Front face of PC enclosure 

Types (1) & (2) require both hands' simultaneous or continuous unlock operation, and is not comfortable for handicapped PC users. Type (3) is better than Types (1) & (2) as it enables one hand unlock operation, but may not be comfortable for left-handed PC users. Some PCs introduced Type (3) mechanism, but its binding strength become degraded as their two latches are aligned in the same holding direction, not like Types (1) & (2).

Summary of Invention :

This invention enables portable PC users to unlock and open a clamshell-designed PC easily and comfortably by either right or left hand, freely from the physical restraint. Two pairs of operation knobs/latches are located facing each other in the front face of PC enclosure, and can be operated by one action. Also the facing latches are holding the foldable LCD panel firmly onto CPU main body against external forces which may cause warpage or distortion to LCD panel....
